What's this?

This is an experiment with making gunicorn gracefully scale down to zero after X seconds, as a way to do application-level scale-to-zero behaviour in applications that use a webserver like Gunicorn. The idea here is that you do not need to mess too much internal logic of an existing application, nor put it in a container if you use this.

Instead you use the web server's own support for handling SIGTERM signals, to allow gracefully scaling down of processes when they are not in use.

If you're using Linux to run a server, the chances of Systemd being used to manage your processes is fairly high, as it's the default option for a number of linux distributions now.

It also means you might not need a complicated "serverless" system to orchestrate scaling up and down, to reclaim memory on a server for us in other tasks if you have a website or webservice that isn't continually serving traffic.

Grace for submission to the Regent House under Special Ordinance A (ii) 5 (fossil fuel industry ties)

21 July 2022

The Council has received the following Grace, which has been initiated under Special Ordinance A (ii) 5 by 84 members of the Regent House:

The University of Cambridge has a strong, stated commitment to addressing the climate crisis and to keeping global heating below a 1.5 degrees Celsius increase from pre‐industrial levels.

The University currently maintains research funding partnerships with major fossil fuel companies, including Shell and BP (https://www.cam.ac.uk/about‐research/energy‐sector‐partnerships).

It’s the next HomeCamp tomorrow. And in a spectacular feat of bad calendaring, I’ve managed to organise the Letter Lounge to take place on the day I’ve been looking forward to for the last few months are coming away from the initial HomeCamp, utterly inspired by what I saw there.

So to make up for not being able to attend, the least I can do is finally get round to writing about the Tealight, a fun, Homecampy little project James Gardner and I built one evening in the Hub recently.

We did it partly to learn about the Arduino platform, and partly to explore how to make something as complex as demand response intelligible to people who don’t think about this for a living, and well here it is, in all it’s janky, low budget hackish glory:
